Description

Technical Field

[0001] The invention relates to the technical field of soil porosity detection, and in particular to a parameter detection device for frozen soil. Background Art

[0002] Since unsaturated silty clay is a common frost-heaving sensitive soil in cold regions, its frost-heaving deformation can easily induce engineering diseases such as roadbed deformation, culvert cracking, and pile foundation uplift in cold regions. Porosity is one of the important factors affecting the frost-heaving mechanism, and roadbed frozen soil diseases are a major problem that plagues various construction projects in my country. Therefore, it is necessary to measure porosity to evaluate and prevent these engineering diseases. At present, the morphology, size and distribution of soil pores are generally obtained by indirect analysis or direct observation. Commonly used detection methods include bulk density method, moisture characteristic curve method, mercury injection method, gas adsorption method, soil slicing method, computer tomography technology and nuclear magnetic resonance technology.

[0003] The prior art discloses an in-situ soil porosity detection device based on an industrial camera and a method for using the device, with publication number CN116448642A. The detection device has a small and compact structure, and is based on layered image acquisition by an industrial camera to eliminate single-layer random errors. It can quickly and accurately detect soil porosity by combining computer vision and machine learning, thereby quickly grasping the spatial variability of soil porosity, saving time and effort, and the detection device has high detection accuracy.

[0004] Although the above-mentioned device can quickly detect the porosity of the soil, there are still some defects in actual use. Since multiple samples are taken for testing each time, and the geotechnical test regulations stipulate that soil porosity testing must integrate three or more groups of experimental data to ensure the accuracy of soil parameter testing in the area, the detection device can only test the soil sample in one ring knife at a time, and cannot test multiple samples at the same time. In addition, the tester needs to replace the ring knife soil sample after each test, which is not only time-consuming and labor-intensive, but also greatly reduces the detection efficiency of the device.

An arc-shaped right-angle block 15 with an inclined surface is provided at the bottom end of the circular frame 13 and located above the circular hole 8. A pair of straight rods 16 are fixedly connected to the bottom of the arc-shaped right-angle block 15. A scraper 17 is fixedly connected between the bottoms of the straight rods 16. A push rod 18 is fixedly connected to the outer wall of the circular plate 14 and located above the arc-shaped right-angle block 15. A U-shaped frame 19 arranged inside the circular frame 13 is fixedly connected to the inside of the circular plate 14. A rectangular groove for the U-shaped frame 19 to slide up and down is provided on the inside of the circular frame 13 to avoid hindering the normal up and down sliding of the U-shaped frame 19. A moving rod 20 is slidably connected through the side wall of the U-shaped frame 19, and a plurality of straight grooves 21 and a plurality of inclined grooves 22 are equidistantly provided on the outer wall of the round rod 4 and at positions corresponding to the moving rod 20.

The bottom of the plurality of straight grooves 21 are provided with inwardly sunken grooves 23, and the connection between the grooves 23 and the inclined grooves 22 is inclined. A pair of lower electric telescopic cylinders 27 are fixedly connected to the top of the detection box 1, and the output end of the lower electric telescopic cylinder 27 passes through the detection box 1 and is fixedly connected to the top of the circular plate 14; The bottom of the push rod 18 is set to a smooth arc surface, and a slide groove 24 is provided at the bottom of the round frame 13 and at a position corresponding to the straight rod 16. The setting of the slide groove 24 avoids hindering the normal sliding of the straight rod 16. An upper spring 25 is fixedly connected between the side wall of the arc right-angle block 15 and the inner side of the round frame 13. The upper spring 25 facilitates the push rod 18 to move away and release the squeezing of the arc right-angle block 15, and quickly pushes the arc right-angle block 15 to reset. A lower spring 26 is fixedly connected between the outer wall of the moving rod 20 and the inner side of the U-shaped frame 19. The setting of the lower spring 26 facilitates the moving rod 20 to be pushed into the groove 23 to ensure the normal operation of the device. The end of the moving rod 20 is set to a smooth arc surface, which can make the moving rod 20 slide out of the groove 23 more smoothly. The number of straight grooves 21 and inclined grooves 22 is the same as the number of round holes 8; The pushing mechanism includes a piston 10, and there are several pistons 10. The top of the lower disc 6 and below the circular hole 8 are fixedly connected with an upper electric telescopic cylinder 9. Several pistons 10 are arranged on the inner side of the circular hole 8 below. The output end of the upper electric telescopic cylinder 9 is fixedly connected to the bottom end of the piston 10. The outer wall of the circular frame 13 and above the circular hole 8 are fixedly connected with a position sensor 39. It should be noted that before use, the position sensor 39 needs to be set to transmit to the receiving sensor 40 to control the start distance of the upper electric telescopic cylinder 9, and the driving distance instructions set for each position sensor 39 are different, which are incremental instructions. For the position sensor 39 that is not next to the discharging mechanism, after controlling the upper electric telescopic cylinder 9 to rise, the upper electric telescopic cylinder 9 retraction instruction needs to be set to avoid affecting the normal operation of the subsequent discharging mechanism. The outer wall of the lower disc 6 and the corresponding position of the upper electric telescopic cylinder 9 are fixedly connected with a receiving sensor 40, and the receiving sensor 40 is electrically connected to the upper electric telescopic cylinder 9 through the controller; Before testing, the ring knife with the soil sample to be tested is placed on the feeding mechanism, and then the ring knife is pushed into the circular cavity 7 in sequence through the feeding mechanism, and the box door 2 is closed. Then the lower electric telescopic cylinder 27 is controlled to start and drive the circular plate 14 to move downward, and then the push rod 18 on the side wall of the circular plate 14 moves downward, and then the arc surface at the bottom of the push rod 18 squeezes the inclined surface of the arc right-angle block 15, so that multiple arc right-angle blocks 15 slide outward at the same time, and drive the straight rod 16 and the scraper 17 to slide outward, and gradually compress the upper spring 25, at the same time, the moving rod 20 is driven to slide inside the straight groove 21, so that the moving rod 20 moves to the side of the groove 23 at the bottom of the straight groove 21, and then the moving rod 20 is pushed into the groove 23 under the elastic force of the lower spring 26, and then the lower electric telescopic cylinder 27 is controlled to retract, driving the circular plate 14 to move upward, and then driving the push rod 18 to move upward to gradually release the squeezing of the arc right angle block 15, and then the arc right angle block 15 is pushed to reset under the elastic force of the upper spring 25, and the scraper 17 is driven to reset at the same time; At the same time, the moving rod 20 is stuck in the groove 23. Since there is a step between the groove 23 and the straight groove 21, it is restricted. Therefore, when the lower electric telescopic cylinder 27 pulls the circular plate 14 and the moving rod 20 to move upward (and since the moving rod 20 is restricted by the circular plate 14 and can only move up and down), the moving rod 20 squeezes the round rod 4 to rotate, so that the moving rod 20 slides out of the groove 23 and slides into the inclined groove 22, and gradually squeezes the moving rod 20 outward, while stretching the lower spring 26, and the rotation of the round rod 4 will drive the upper disc 5 and the lower disc 6 to rotate, so that the feeding frame 12 is moved to the side. The circular cavity 7 rotates to the bottom of the shooting and analysis module 3, and then the moving rod 20 slides out of the inclined groove 22 and slides into the straight groove 21. At the same time, the receiving sensor 40 under the corresponding circular cavity 7 rotates to the bottom of the position sensor 39. The position sensor 39 will transmit the instruction to the receiving sensor 40. The receiving sensor 40 controls the upper electric telescopic cylinder 9 to move upward a certain distance, thereby driving the piston 10 to move upward in the ring cutter, pushing the frozen soil sample in the ring cutter upward a certain distance, and then controlling the lower electric telescopic cylinder 27 to start repeating the above operation, and repeating this process to realize automatic detection of frozen soil samples in multiple ring cutters.

[0022] In order to facilitate the centralized collection and processing of the pushed out soil samples, a U-shaped collection frame 28 is slidably connected to the bottom end of the detection box 1 and below the lower disc 6. The setting of the U-shaped collection frame 28 facilitates the centralized collection and processing of the soil samples pushed out by the scraper 17, which in turn facilitates the subsequent unified processing, and will not hinder the normal rotation of the round rod 4, thereby improving the convenience of the device.

[0023] In order to realize automatic loading and unloading of the device, the feeding mechanism includes a feeding spring 29, the inner bottom end of the feeding frame 12 is flush with the bottom end of the circular cavity 7, a moving groove is provided at the inner bottom end of the feeding frame 12, a pushing plate 30 is slidably connected to the inner side of the moving groove, the feeding spring 29 is fixedly connected between the side wall of the pushing plate 30 and the inner side of the moving groove, the bottom of the circular frame 13 is fixedly connected to the top of a three-quarter circular limiting plate 31 through a plurality of connecting plates 41, and the limiting plate 31 is arranged on the outer side of the circular cavity 7; The discharging mechanism includes an electric telescopic cylinder 32 for discharging, a cavity is provided inside the circular cavity 7, a discharging plate 33 is slidably connected inside the cavity, and a top rod 34 arranged through the top of the upper disc 5 is fixedly connected to the top of the discharging plate 33, a return spring 36 is fixedly connected between the inner side of the cavity and the side wall of the discharging plate 33, the electric telescopic cylinder 32 for discharging is arranged above the upper disc 5, and is located at the rear side of the circular cavity 7 corresponding to the discharging frame 35, and the three-quarter circular limit plate 31 cannot block the circular cavity 7 corresponding to the loading mechanism and the discharging mechanism, and the discharging frame 35 is obliquely penetrated and fixedly connected at the rear side of the detection box 1 and at a position corresponding to one of the circular cavities 7, the outer wall of the electric telescopic cylinder 32 for discharging is fixedly connected to a support frame 37, and the position of the electric telescopic cylinder 32 for discharging is fixedly supported by the support frame 37, the top of the support frame 37 is fixedly connected to the top of the detection box 1, and the output end of the electric telescopic cylinder 32 for discharging is arranged at a position corresponding to one of the push rods 34; Before testing, a material box needs to be placed under the discharge frame 35 at the rear side of the test box 1, and the box door 2 is opened at the same time. The push plate 30 is pulled to slide in the moving groove, and the feed spring 29 is gradually compressed. Then, the ring knives to be tested are placed next to the push plate 30 in turn, and under the pressure of the feed spring 29, the frontmost ring knives on the feed frame 12 are pressed against the side wall of the upper disc 5, and the discharged ring knives are collected. During the testing of the frozen soil sample in the ring knives, the ring knives after the test are rotated to the side of the discharge frame 35 under the continuous drive of the lower electric telescopic cylinder 27. (and before moving, the position sensor 39 will control the corresponding upper electric telescopic cylinder 9 to reset to avoid affecting the normal push-out of the subsequent ring knife), so that the ring knife is rotated out from the limit plate 31, and the position restriction of the ring knife is released. Then, the corresponding push rod 34 is pushed to move by controlling the discharge electric telescopic cylinder 32, thereby driving the discharge plate 33 to slide inside the circular cavity 7, and gradually stretching the reset spring 36, so as to push the ring knife in the circular cavity 7 out and onto the discharge frame 35, and then slide down under the gravity of the ring knife itself, thereby realizing the automatic discharge of the ring knife; Subsequently, under the continued drive of the lower electric telescopic cylinder 27, the empty circular cavity 7 is rotated to the side of the feed frame 12, thereby squeezing the frontmost ring knife of the feed frame 12, and then the push plate 30 is pushed to move under the elastic force of the feed spring 29, thereby pushing the ring knife into the empty circular cavity 7, and then the ring knife is rotated away under the drive of the lower electric telescopic cylinder 27, and the size of the circular cavity 7 is the same as the size of the ring knife. Therefore, when the upper disc 5 rotates away, the ring knife on the feed frame 12 is squeezed by the ring knife in the circular cavity 7, so that the ring knife in the feed frame 12 is located on the outer wall of the upper disc 5, so it will not hinder the normal rotation of the upper disc 5. This is repeated to realize automatic loading and unloading of the device, and there is no need for the inspection personnel to open the box door 2 many times for layout operations, further improving the inspection efficiency of the device.

[0024] In order to improve the detection efficiency of the device, a number of shielding curtains 38 are fixedly connected to the rear side of the detection box 1 and above the discharge frame 35. The setting of the shielding curtains 38 can ensure that a certain sealed space is maintained in the detection box 1 to prevent external light sources from affecting the normal detection of the shooting and analysis module 3, thereby improving the detection efficiency of frozen soil.
